oil or liquid, which can be drawn through the common discharge ,pipe,.the object for which will behereinafter described; WVithin the cup 7 and a nnlformly spaced distance from the 55 cylinder area plurality of valve cagechame bers 27. At the bottom oi each valve cage opening an auxiliary chamber 40 ofless' diameter than the valve cage chamber: A lead 37 -connectschamber 4O with a pipe 62, 60 which pipe leads to the source of supply of the oil or fiuidto'be dispensed, In Figv II have shown pipe 62 entering a tank partly" filled with liquid 6-3,,a compressed air re'ser- I voir 32, and aiconnection between, the top" of the tanlr andthe compressed air reservoir, sora constant pressure of air can be had on thetop of the liquid in tank 33. I ,A galve cage 22 is formed to fit. Withinthfe valve cage chamber, said valve cage having ing a valveseat fie formed at thebet'tom. A valve-2O is adapted tocooperate with the valve seat 65. a The top ofthe'valve cage 19 is, adapted as a closure for thev'alve cage chainhe'r and also as -a guide for the SiZEIIL'Of valve 2O. It is noted that the relation ofthe' valve seat and the-valveis that the pressure a of the oil or, liquid through lead 37 Will tend to keep the valve closed, and on opening the valve, chamber 'iseadapted to receive the I head of the valve so the fluid can flow through opening37,?anound the valve and into the valve cage. f p r i From each valve cage and valve cage chan1- her is a lead 28 to cylinder 54, all ofwhich openings should be. aligned on a common plane aspa'ced distance from the bottom; of the cylinden: 7' 5 I j The rotor has a conduit 6textending'froin' the bottom of the rotor" to a fixed locationon its periphery, positioned so that one endof the leadfis constantlyopen into 'well36' regardless'ofthe position of the rotorwithin thecylind gland theotherend of the conduit aligned to with each of the leads 8 as the rotor i s turned onits axis. It will e seen that by rotating the rotor the operwe can selectively register [a complete open net frorn the discharge pipe 29' to either, of

the plurality of tanks shown excepting for the restrictions of valves 20.

The to of the valve stem terminates with a base 1 and by inserting a compression spring 18 between base 17 and closure 19, the valve will normally be kept closed. To open the valve I have pivoted one end of lever 16 to a depending lug on the under side of top or cover 13, a spaced distance from the center of said top and have positioned the lever parallel to a radius of the cover so that the free end thereof is adj acent to the center line of the cover. The lever will rotate with the cover, and a portion of the lever between the pivoted and free ends will pass over the tops of the valves in such rotation. A plunger 11 is adapted to cooperate with the free end of lever 16. The position of lever 16 and lead 64 are such that when lead 64 registers with the opening 28 of any valve cage chamber the lever will be positioned over the valve stem cooperating with that one valve cage chamber. When the lever is positioned over a selected valve, by depressing plunger 11, said selected valve will be opened and the other valves will be normally closed by means of spring 18. The plunger stem is easily depressed by pressing on the top of plunger headlO.

For the purpose of returning the plunger and lever to an inoperative position, and for releasing the lever from the base of the valve stem so the cover and rotor can be freely rotated, I have provided'an auxiliary compression spring 23 which is depressed when the plunger is depressed and holding the valve open. On the release of pressure from the plunger, lever 16 and plunger 11 is raised. A cap 24 covers the top of spring 23, forming a head for spring 23. Spring 23 and cap 24 are contained in the hollow portion of stem 60. A hole 67 through knob 12 serves as a guide for the plunger. A slot 25 in stem serves as a guide for the free end of lever 16, and

' also acts as a stop to limit the up and down movement of lever 16 and thereby limit the opening of the valve.

An indicator 9 is attached to a fixed point on block 50. When it is desired to dispense a special brand of oil, as for instance the A brand, the cover is rotated so that the A design is adjacent to. the indicator. The opening 28 in the chamber having direct communication to the tank of oil also designated A will then register with conduit 64, and

lever 16 will be in operative relation with valve 20 of the same chamber, and that valve only can be opened to function to discharge the oil. I It is here noted that the oil can be discharged from the tank by air pressure as shown, but pumping or other well known means can be used to discharge the oil or li%id.

or the purpose ofholding the cover in positlon over the selected valve, I have attached a catch and spring assembly 8 to the under side of the cover, and have formed a notch 14 on the inside wall of cup 61. When the rotor and cover are turned to cooperate with any one selected valve, the catch will engage one of the notches 14. Block 50 has a circular recess 51 formed on the periphery adjacent to the bottom end to receive housing 31 which is intended to cover the pipes 62 and any reservoir or other accessories desired to be placed therein. To thishousing I have attached a bracket 34 for convenience in supporting the measure or container into which the liquid is drawn.

I claim as my invention:

1. In a liquid dispensing device the combi nation of a block having a cylindrical opening therein, a rotor adapted to fit and turn freely within the cylindrical opening, a plurality of valve chambers in said block,'each of said chambers having one lead to a source of liquid supply and a second lead to the cylindrical opening, a well in said block having a discharge opening therefrom, a conduit through the rotor positioned within the rotor so one end of said conduit opens into said well and the other end is adapted to selectively register with the lead to either one of said plurality of chambers, separate valve means for normally closing the flow of liquid to each of the valve chambers, means for i I normally keeping all of said valves in a closed relation and means for opening the valve within either of said valve chambers,

when the conduit and lead in said valve chamber registers.

2. In a liquid dispensing device thecombination of a block having a cylindrical opening therein, a plurality of valve chambers positioned within said block equi-distant from the wall of the cylindrical opening, each valve chamber having a lead to a source of liquid supply and a separate lead to the cylindrical opening, the leads to the cylindrical opening being all aligned on the wall of a common cross section of the cylindrical opening, a rotor adapted to fit and to rotate within the cylindrical opening, a well formed within the block adjacent to the bottom of cylindrical opening, a discharge opening connected with said well, a conduit through the rotor one end of which communicates constantly with said well in the rotation of the rotor, the other end of said conduit being adapted to register with each of the leads into the cylindrical opening during the rotation of said rotor, and to register with one only at a time, a dial attached to the rotor having designations thereon for each of the plurality of valve chambers, a valve in each valve chamber adapted to cut off the flow of liquid into the valve chamber, separate means for each valve adapted to close said valves, means attached to the dial and rotatable therewith adapted to open either of said valves, said opening means being positioned on the dial so the opening i meanswill be in operative relation only with the valve Within the valve chamber connected with the "well through said lead and conduit; hand means for opening said valve when the valve and opening m'eansare in operative relation.
